This work presents an original experimental device conceived to characterise the viscoelastic properties of wood. Classically, the dynamic mechanical analysis of wood is performed using a commercial apparatus like a DMA (Dynamic Mechanical Analyser).

In this paper, the viscoelastic properties of wood under water-saturated conditions are investigated from 10\degree C to 135\degree C using the WAVET* apparatus. Experiments were performed via harmonic tests at two frequencies (0.1 Hz and 1 Hz) for s

This paper proposes a new inverse method to identify Kelvin's elements simultaneously from several creep tests carried out at different temperature levels. The dimensionless formulation derived for this approach allows thermally activated Kelvin's el
